HyperKalemia - Potassium increase - Causes, level, diagnosis and Rx:
Hyperkalemia - increase in the level of potassium Causes, level, diagnosis and Rx: s-K> 5.5mmol/l requires emergency management: ECG, repeat bloods, stop exogenous potassium and potassium retaining medications Assess potential causes of transcellular shift estimate the GFR Drugs: ACE inhibitors, Potassium sparing drugs, digitalis toxicity (blocks the Na/K ATPase, Succinylcholine, B-Blockers Potassium Supliments - Potassium Chloride suppliments or KCl IVI PEN G - antibioltics Breakup of cells: Rhabdomyolysis, tumour lysis syndrome, Hemolysis - the intracellular K leaks out to the extracellular space - increasing potassium in the blood Metabolic Acidosis (except for keto and lactic acidosis) and Insulin deficiency - DKA - both acidosis and insulin deficiency Potassium can not be excreated decreased GFR renal failure decreased effective circulating volume NSAID in renal insufficiency HYPOALDOSTERONISM Causes of Hyerkalemia with Normal...
